SPECIFICATION forming part of Letters Patent No. 555,171, dated February25, 1896.

Application filed December 4., 1895. Serial No. 571,011. (No model.)

To aZZ whom it ntcty concern.-

Be it known that 1, CHARLES HENRY KRATJSS, of J ohnstown, county ofOambria, State of Pennsylvania, have invented a new and usefulImprovement in Railway Switches, of which the following specification isa true and exact description, due reference being had to theaccompanying drawings.

My invention relates to that class of switches in which there is atongue hinged upon avertical pivot near one end, and has for its objectto provide a means for holding the tongue down in place.

Referring to the drawings, Figure 1 represents a top view of a switchembodying my invention. Fig. 2 is a vertical section through thefastening. Figs. 3 to Sshow various pieces in detail, as will behereinafter described.

In general a switch embodying my invention has a hole through thetongue, a bolt passing through the hole and engaging a spring placed inthe frame of the switch, the whole being so arranged that the springact-- ing upon the bolt serves to hold the tongue 2 5 down in place.

In the drawings, A is the frame of the switch and B the tongue hingedupon the pin C.

In the frame of the switch I form the pocket D near the pivot -pin 0,and through the 0 tongue there is a hole above the pocket D. The top ofpocket D is closed by the washer E, also having a hole concentric withthat in the tongue. The shape of this washer is clearly shown in Figs. 5and 6, in which it is 5 seen that it has the locking-flanges 6 adaptedto register with corresponding flanges 6 111 the top of pocket D, thewhole being so arranged that the washer may be dropped in from above andlocked therein by a slight turn. Passing through the tongue and washeris the bolt F, and surrounding the bolt is spring II.

In the top of the tongue the hole is enlarged to receive the washer 1.(Shown in detail in 5 Figs. 3 and at.) This washer has the oblong holeshown, and the upper end of the bolt is correspondingly flattened on thesides. The bolt F, as is shown in Figs. 7 and 8, has a recess formed init at f, so that the washer I is free to turn upon it at this point.

The method of assembling the parts is as follows: Before the tongue isplaced in the frame the bolt F and spring H are placed in pocket D. Thewasher E is then dropped into place and given a turn to lock it. Nextthe tongue is put in so that the end of boltF projects above it, andwasher I is then slipped over top of the bolt. By means of a hook orlever inserted in the hole in the top of the bolt it (the bolt) is thendrawn up until washer I registers with groove f, when it is turnedaround. This pulling up of the bolt compresses spring H, and ittherefore exerts a downward pull on the tongue. The top of the bolt isthen out off, it having been previously grooved at f for this purpose,and, if desired, the cavity around it maybe filled with lead or otherfilling substance L. To remove the tongue it is necessary to firstremove this filling substance and by means of 7 0 a wuench turn bolt Funtil it will pass downward through washer I, when the tongue may belifted out.

Having thus described my invention, what I claim, and desire to protectby Letters Patent, is

1. In a railway-switch, a tongue-fastening comprising a bolt extendingvertically downward from the tongue, and a spring in the frame of theswitch and adapted to exert a downward force upon the bolt.

2. In a railway-switch, a tongue-fastening comprising a bolt passingthrough the tongue and removably secured therein, said bolt passingdownward into a pocket in the switch- 8 5 frame, and a spring encirclingsaid bolt and adapted to exert a downward force thereupon.

3. In a railway-switch having a verticallypivoted tongue, a pocket inthe frame of the switch and beneath the tongue, a spring in said pocketand a bolt depending from the tongue and engaging the spring.

4. In a railway-switch having a verticallypivoted tongue, an orifice inthe frame of the switch and beneath the tongue, a member removablysecured in the mouth of said orifice, a spring in said orifice andadapted to engage said member and .a bolt removably secured to thetongue and passing down through said member and engaging said spring Intestimony whereof I have affixed my signature in presence of twowitnesses.

CHARLES HENRY KRAUSS.
